Bar heights represent mean responses across three biological replicates. Dots show individual replicates and error bars show the range. Letters indicate the results of a statistical test, where bars labelled with the same letter have statistically indistinguishable means (one way ANOVA, α = 0.05, followed by Tukey posthoc test). Arrows indicate initial concentrations. Circled numbers are experiment sampling sites.
